Which of the following are the correct properties of slope?
check all that apply.

A and E.

Explanation:

A slope is part of the definition of a lineal function, with it we can know the behaviour of the function graph. This is crucial to lineal models applied to real problems.

So, when a line moves up from left to right, we say that has a positive slope.

On the other hand, when it moves down from left to right, we say is negative.

But, there are cases when lines don't have a specific slope, for example, vertical lines have undefined slope, because their inclination tend to infinite.
